TRACE- HOOK.

SPECIFIGATION forming part of Letters Patent No. 424,950, dated April 8, 1890.

Application filed February 21, 1890. Serial No. 341,297. (No model.)

To all whom, it may concern:

Be it known that I, PETER BARTZEN, a citizen of the United States, residing at Huron, in thecounty of Erie and State of Ohio, have invented a new and useful Traoelloolg, of which the following isa specification.

rIhe invention relates to improvements in trace-hooks.

The object of the present invention is to provide a simple and inexpensive trace-hook adapted to be readily secured to a whiftletree of the ordinary construction and capable of enabling a heavy load to be gradually started without jars to the animal and to prevent jars during the passage of the vehicle over rough surfaces.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed vout in the claims hereto appended.

In the drawings, Figure l is a perspective View of a whifletree provided with a tracehook constructed in accordance with the invention. Fig. 2 is a detail view of the hook detached. Fig. 3 is a similar view of the T- shaped plate. Fig. L is a plan view of one end of the whiiicletree, showing how the spring trace-hook is pulled forward by the draft.

Referring to the accompanying drawings, l designates a whiffletree which is provided near its end with a T-shaped plate 2, that is constructed of metal, and is secured to the rear face of the wliiffletree, and has its arm 3 perforated and secured to the whifletree by a screw 4, and the arms 5 and 6, arranged at, right angles to the arm 3, rounded and adapted to receive coils or eyes 7, that are formed in a whiiiietree-hook S. The whifletree-hook is constructed of a single piece of spring-wire that is doubled and formed approximately U-shaped to enable it to fit around a whifietree, and has its sides 9 bent at right angles and provided at the bends with eyes 7, that are formed by coiling the wire.

The extreme ends of the wire forming the trace-hook are twisted and bent into the form of a hook and adapted to readily be connected to the end of a trace. By this construction as soon as an animal attempts tol start a loaded vehicle his force will rst be exerted against the spring of the trace-hook and then upon the load, by which means any sudden jars in starting heavy loads are prevented, and jars are also prevented while the vehicle is passing over uneven surfaces.

From the foregoing description and the accompanying drawings the construction, operation, and advantages of the invention will readily be understood.

What I claim isl. A trace-hook adapted to be pivoted to a whifiietree and constructed of a single piece of spring-wire doubled a-nd embracing the whiliietree at the end, and having its sides bent approximately at right angles and the ends of the wire formed into a hook, said sides being provided at their bends with coils forming eyes by which the hook is pivoted, substantially as and for the purpose described.

2. The combination of the T-shaped plate, adapted to be secured to a whiiiietree, and having its arms 5 and G arranged to project beyond the whiilletreev and being rounded, and the trace-hook constructed of a single piece of spring-wire doubled, and having its sides bent at an angle and its ends twisted and formed into a hook, said sides being provided at their bends with coils forming eyes adapted to receive the rounded arms of the T-shaped plate, substantially as and for the purpose described.

In testimony that l claim the foregoing as In y own I have hereto affixed my signaturein presence of two witnesses.
